1. Introduction

Ginger (Zingiber officinale Roscoe) is an economically important plant, valued all over the world for its medicinal properties. It has a respected history as a spice crop and is known to human generation since time immemorial (Anonymous, 1950). It is used in medicine as a carminative and an aromatic stimulant to the gastrointestinal tract and externally as a rubefacient and counter irritant (Rout and Das, 2002). The use of ginger oil and oleoresin in various food and drink items has increased its economic importance in the global market. The rhizome is also used as an antidiarrheal medicine in its powdered form. Phytochemical, pharmacological and toxicological properties of ginger have been reported by Ali et al., 2008. Many common ginger cultivars in India are mainly recognized by their locality of cultivation/ collection. The differentiation of the cultivars rather difficult due to absence of clear-cut morphological features coupled with the lack of specific characters (Shamina et al., 1997). So biochemical and molecular markers presume significance. The use of biochemical markers for germplasms characterization has been seen in several crops (Weeden and Weeden, 1985; Al-Jibojuri and Adham, 1990; Demiera and Vega, 1991; Bhat et al., 1992; Bult and Kiyangi, 1992). The chemistry of ginger is well documented with the respect to the oleoresin and volatile oil (Barnes et al., 2002; Sweetman, 2007). More than 400 chemicals have been identified in ginger rhizome (Garner-Wizard et al., 2006). The relative proportions of chemicals were determined by geographical location and age of rhizome during harvesting and extraction method. Chemical constituents of ginger categorised to volatile oils which constitutes (1–3%) mainly of zingeberene (Robbers et al., 1996) nonvolatile pungent compounds oleo-resin constitute (4–7.5%) mainly gingerols and other constituents with more than 50% of starch (Robbers et al., 1996), many fats, waxes, carbohydrates, vitamins and minerals. A variation of the phytoconstituent was observed when the cultivars were collected from various geographical region (Ravindran and Babu, 2004). The available genetic resources can be utilized to improving the plant by diversity characterization. Conventionally, genetic diversity assessment was confined to morphological observations and progeny evaluation, but they had restriction of being plastic and environmentally-sensitive. During the past two decades, molecular markers have been widely used to overcome these de- ficiencies. At present the molecular marker techniques have revealed their potential and wide range of significance in recognizing genetic purity of germplasm stocks (Joshi et al., 2000), understanding genome organization, frequency and level of diversity in large and complex genomes (Blair et al., 1999), identifying genetic relationships (Tsumura et al., 1996), chromosome mapping (Giura and Saulescu, 1996), trait tagging and inheritance (Kelly et al., 2003) and molecular breeding (Gupta and Varshney, 2000). Inter-simple sequence repeat (ISSR) is a molecular marker which is a fast, inexpensive genotyping technique based on variation in the regions between microsatellites. ISSR markers are more reproducible than RAPD and have been proven to be a simple and reliable marker system for many organisms, especially plants, with highly reproducible results and abundant polymorphisms. ISSRs have been successfully used to estimate the extent of genetic diversity at inter- and intra-specific level in a wide range of crop species which include fingermillet, Vigna Savi, sweet potato, and Plantago major L. It has also been used for resolving problems relating to the phylogeny of Asian cultivated rice Oryza sativa L. (Joshi et al., 2000), wheat, and Diplotaxis DC. species. Literature states that there is a lack of information about the chemical and molecular characterization of ginger from Odisha. The present work is an attempt to characterize 20 selected accessions of ginger germplasms available at HARS, Pottangi based on its Isozyme estimation and metabolite (protein, phenol and fiber) contents and their molecular characterization.
